Hello, I've been asked to shoot costumes at a Halloween party and I'm concerned about fill flash. The lens I'll be using is a Nikon AF Nikkor 28-80mm 1.3-5.6G zoom lens. What kind of flash metering should I use and how do I go about setting it? I'll be shooting in auto ISO and would like to shoot in M so I can change my aperture to blur objects behind. There will be some ambient light from the windows and overhead fluorescents. The flash is built in the camera. Thanks
First: when using flash, turn Auto ISO Off. Auto ISO does not work when combined with flash and you will most likely be dissappointed in the images.
Second: in a mixed light situation you might be better off using the flash to overpower the ambient light to minimize the chance of color cast or issues with WB instead of using it for fill. You will have to under expose for the ambient by about 3 stops for the flash to overpower the ambient WB.
On the other hand you could take a few test images to see just how much color cast the flourescent lights add. If the fluorescent bulbs are daylight balanced you might not have a problem with color cast at all. For fill flash, stick with Matrix metering.
>since the flash is built in and not on the hot >shoe will the matrix metering know what kind of flash.
Yes! The built in Speedlight can be used for fill flash as well. See page 94 -95 in the D100 Users Manual. Assuming that you use D-TTL (TTL) Flash control. Note: If you decide to use Manual exposure mode, 3D Multi-Sensor Balanced Fill flash will not be available. You must use P, A, or S exposure modes in order to take advantage of 3-D Multi-Sensor Fill Flash.
>I heard that certain lenses don't work with matrix metering?
The D100 supports 3D Matrix Metering with all D and G type lenses including AF, AF-I, and AF-S lenses. It supports Ten Segment Matrix Metering with pre D type AF lenses and AI-P type lenses. It does not support metering with Non-CPU lenses.
While I don't see any restrictions listed for your 28-80mm in either the D100 or 28-80mm Users Manuals, if you use a lens hood, be aware that you might see a shadow of the lens when using the built-in Speedlight at wider focal lengths and closer camera to subject distances. Just something to be aware of.
Fred, Don't exclude trying the camera in "P" (Program) Mode with the flash. Let the camera decide how much flash is needed to get the proper exposure with the available light. Shoot in RAW to ensure you have the flexibility to make adjustment during post processing.
